Mcafee install and javascript error

We're having trouble installing your mcafee software because JavaScript is not working correctly on this pc.

I tried to do a restoral to an earlier time but the system restore window comes up white. Also the field on the search window to search for files are not there, just black on the left hand side with that stupid dog. Someone please help! I work from home and this may mess me up for my shift tomorrow morning. Thank you!
